Fan drive control improves piston pump performanceWith the aim of increasing system efficiency and improving machine performance, Danfoss Power Solutions has developed a fan drive control feature for its Series 45 portfolio of open circuit axial piston pumps.

Available on K2, J and F frames, this intelligent thermal management solution can maximise cooling efficiency, decrease fuel costs and increase operator productivity.

“The lower minimum system pressures allowed by the fan drive control result in slower minimum fan speeds, which improves fan drive system efficiency,” said Jeff Brenner, Director of Open Circuit Medium Power Sales at Danfoss Power Solutions. “It also offers a variety of benefits for low cooling requirement conditions, including reduced fan noise.”

Features and benefits include:

  • Improved performance with better control resolution
  • Smaller package size that is up to 2.2kg lighter than the current electronic pressure control (EPC)
  • Optimised design for easy tuning and setup, and better serviceability

The Series 45 fan drive control can also improve machine performance when used in conjunction with a Danfoss Reverse Displacement Motor (RDM) — the RDM uses less power and eliminates the heat generated by traditional reversing systems to help machines run more smoothly. And the RDM also uses fewer components, such as hoses, valves, and HIC blocks, leaving more space in the engine compartment and reducing costs.

“The Danfoss Reverse Displacement Motor is just one of the many product innovations and system solutions created by our continuous improvement and re-engineering effort,” said Brenner. “By eliminating the directional control valve and integrating the shift valve into the RDM, we have engineered a solution that is both cost-effective and energy-efficient.”
